This Equation Has One Solution., 5(X 2013 1) + 3x = 7(X + 1), What Is The Solution?
This equation has one solution.
5(x – 1) + 3x = 7(x + 1)
What is the solution?
Answer:
12
Step-by-step explanation:
step 1: Distribute all under with the parenthesis
5(x – 1) + 3x = 7(x + 1)
⇒ 5x -5 +3x = 7x +7
step 2: move all the variables (those with x) to the left side and all constants to the right side
remember: the sign will change when moving to another side (+ to - or - to +)
5x + 3x - 7x = 7 + 5
step 3: simplify (combine like terms)
x = 12
